     Thank you so much for the information.

Now i compared "arch/arm/boot/dts/r8a7779-marzen.dts" against  "arch/arm/boot/dts/r8a7794-alt.dts" and modified r8a7794-alt.dts a little..
also added  "thc63lvdm87"in "drivers/gpu/drm/rcar-du/rcar_du_kms.c"..here i am attaching the modified 
r8a7794-alt.dts file..I am a newby in this field so that I am asking very basics..hope you don't feel bore..
I also build image file and .dtb file successfully but don't deployed it..
if you don't mind can you please give me a feedback of my work..My source tree is v4.7.5

PFA

Best Regards
Jithin T Raj
